seperate sacs same placenta

Today we had our 3rd growth ultrasound. During every other ultrasound we've had, the boys have had two separate sacs and two separate placenta's. But today they were not able to identify 2 placenta's. So I am wondering what does it mean if they share a placenta but are in 2 separate sacs? I dont exactly know.

Also both boys are doing well! they are measuring very well and both are about 2 pounds. And im just 25 weeks and 1 day!

The placentas probably fused into one because they were leaning against each other. At each U/S we have had the doc has said that he thinks we have two separate sacs and placentas that have fused because they implanted to closely together. 85% of twins with separate sacs and placentas are fraternal, but 15% are still identical- it all depends on when the egg split, so you won't know much more until after they are born as to whether they are frat or id- get a DNA test if you want to know. If the placentas were separate until now, you probably don't have to worry about TTTS, but should ask about that anyway. Good luck! :)

If they actually share a placenta they are identical, as you found out at delivery. They can sometimes tell by looking at the placenta after delivery if it was defianately one or could have been two. In the womb it can be hard to tell if two placentas have fused or if there is actually one placenta depending at what point you have your first ultrasound. They still aren't sure about my girls, we'll see after I deliver if it looks like one or two fused together, or if we have to, we'll have a DNA test. :)

hi,

my girls share a placenta and are in two separate sacs..but they were like this from the begining (8 weeks when we found first). so they are identical.

but if you had 2 placenta n now you see only one they could have fused together and good thing is you dont have to worry abt TTTS ..yay.. ...well you will have to find out doing the DNA test i beleive.

good luck
